LOCATION OF BENZINE TANKS IN AEROPLANES.

Application filed July 8, 1921. Serial No. 483,316.

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L,1313.)

To all whom it mag concern: Be it known that ANTHONY HERMAN GERARDFOKKER, residing at Amsterdam, Rokin 84, Netherlands, has inventedcertain new anduseful Improvements in the Location of 'Benzine Tanks inAeroplanes for which I have filed an application in Germany April 6,1918), of which the following is a specification.

The location of fuel tanks in aeroplanes has always been a source ofdanger, especially for the reason that in case of an ac to be taken intoconsideration as other arbelow the fuselage also had its disadvan tageswhich occurred especially upon starting and landing.

The present invention therefore has for its object the mounting of thefuel'tank within the carriage of the aeroplane without however operationof the carriage in addition .to avoiding the disadvantages recited'inconnection with the previous arrangements.

object of this invention to construct the tank or carriage so that thetank or tanks can be i easily removed and replaced while the location ofthe tank is such that in, case of ignition of the carriage, the coveringthereof maybe destroyed but the fuselage and supporting wings,etc. willnotbe endangered,

interfering with the effective:

. nto

-'as the tanks and supporting bars are shaped to give the flames abackward direction during flight.

Other objects as well as the nature, characteristic features and scopeof 'this invention will be more readily apparent from the foregoingdescription taken in connection with the accompanying drawing andpointed out in the claims forming a part of this specification.

The invention is clearly illustrated in the accompanying drawing, inwhich Fig. 1 is a perspective View of the improved fuel tank arrangementlocated within the covering of the carriage, and

. Fig. 2 is a horizontal sectional view through a slightly modified formof the invention. 1

Referring now, more particularly, to the accompanying drawings there isprovided a carriage structure including a series of suitably spacedcross-bars or ribs a shaped to afiord the least resistance to the airand covered by the envelope or covering b. The fuel tank is locatedtransversely between the cross-bars a and, in the present instance isshown constructed in sect-ions c preferably arranged in front of andbehind the axle (l which latter is reinforced by a bolster or the like ewhich extends through a series of aligning openings positioned mediallyof the cross-bars a as indicated in the drawings. The cross-bars arealso provided with openings forwardly and rearwardly of the axleopenings being indicated by the reference letter f and the tanks 0 aresnugly fitted in these openings. In the arrangement shown in Fig. 1 thesection 0 extends throughout the width of the carriage whereas in thearrangement shown in Fig. 2 the tank sections are further dividedhorizontal aligning sections, the abutting edges being supported in theopenings f in the bars or ribs a. It is an additional and equallyimportant If several tanks are arranged between the cross-bars a, aconnection of the fuel tanks with each other is provided being indicatedplies to the motor are providedlfrom each tank, the connection thereforbeing indicated at i in Fig.2..

It is of course appreciated that the axles are fitted with the usualsupporting wheels is shown in dotted lines in Fig. 1.

It isbelieved in View of the foregoing that a further detaileddescription of the operation is entirely unnecessary. Likewise it isbelieved that the'advantages of the invention will be readily apparent.

Having thus fully described the invention what is claimed and desired tobe secured by Letters Patent is 1. In an aeroplane carriage, thecombination, side b'ars shaped to alford the least possible resistance.to the air, a fuel tank fitted in and supported by said bars, and anenvelope covering the .bars and the tank, substantiall'yas and for thepurposes set forth. I

2. The combination with the spaced side bars of the carriage of anaeroplane of a fuel tank constructed in sections 'and arrangedtransversely between. and fitted in and supported by said bars.

3. In an arrangement as claimed in claim 2 wherein the. sections of.the' tank are shaped shaped to afford the leastpossible resistance tothe air when the aeroplane is iujfiightj fuel tank formed -in separatesections and arranged transversely between the bars and snuglyfittedthrough the openings so as to be supported so as tdafford the leastpossible re sistance flight.
